Guys our worst developer - that would be me, Lobster, has two Rpi boards. The first came two days before general release. Debian, Fedora and Arch have had boards six months ahead of us. More able developers such as Barry, Raffy, Sickgut, Antiloquax (two boards), MarkG, John Murga (has board) and others have boards on order or just arriving.
The Raspberry Puppi is part of PARM.
We are making Puppy available for ARM processors, tablets and smart dog and bones

How do I get an operating system for my Raspberry Pi NOW?

Mark (antiloquax) is working on an ARCH based Puppy in Qemu
We are recommending using Debian and Arch process to get started/familiar
